SPECIFICATION forming part of'LettersrPatent 1\T0.` 282,268, dated July31, 1883. A Application filed April 2e, icas. (Np model.)

.To all whom t may concern,.- 1

Be it known that I, JOHN C. CALHooN, of

New Brighton, Beaver county, Pennsylvania,

have invented certain Improvements in Trusses, of which the following isa specifica out becoming displaced, and it consists in the constructionof parts hereinafter particularly described, and then Asought to bespecifically defined by the claim.

The figure of the drawing is a perspective of the truss with thecovering removed from the spiral spring and pad-plate, so as toillustrate the construction of those parts.

In the Vaccompanying drawing, the letter A indicates the waist strap orband, which has a pad, B, connected to one end, and a bucklestrap, G, atthe other, so-that the waist-strap may be lengthened when necessary. Thepad is made of wood or leather7 and has a plate, D, pivoted to it by apin, a, and a screw-pin, b, passed through the plate into the pad, holdsthe pad at any adjustment desired. The plate D is provided with abutton, E, for thestrap C, and a button, F, for the thigh-strap G, which`is buckled to the slide H. Another strap, I, buckled to the slide H, asshown in dotted lines, is buttoned to the stud J, secured to the waiststrap or band near where the pad-plate isl secured thereto, andisintended to `control the adjustment of the thigh-strap. One end of thepad-plate is pivoted by a rivet, c, between two pieces of leather, K,and two spiral springs, L, connect the plate to the waistband. Thesesprings are held between the leather K by rivets d, passed through eyesor loops at the ends of the springs. The other ends of the springs aresecured in the same manner between leathers M, and these in turn arestitched or otherwise secured between the divided end ofthe waistband. Ahousing, N, is provided 45A with a strip, O, to lie along the pad-plateand coiled springs, so as to protect the same against perspiration, andis then folded over the padfolded, so as to make it strong, and at thesame` timeleave it soft and pliable, so as not to chafe the skin. Clothor rubber may be substituted for leather. y

The spiral springs are rigid enough to cause the pad to bear withsufficient pressure for the purpose against the affected part, and yetflexible enough to conform to the shape of the body, and elastic enoughto yield to longitudinal pressure. This arrangement of the pad rendersthe truss quite easy and comfortable to wear, and the simplicity makesthe truss cheap of production. p

Having described my invention and set forth its merits, what I claim isfIn a ilexible truss, the combination of waistband A, Vpivoted plate D,carrying the pad, the spiral springs L, and the connecting-pieces K, thesprings being secured to the connecting-pieces by rivets and protectedby the flexi ble housing, substantially as described.

` In testimony whereof I have signed my name to this specification inthe presenceof two subscribing witnesses.
